Safe protection supporting column of lifting platform

Abstract

The invention relates to a safe protection supporting column of a lifting platform. The column overcomes deficiencies in the prior art. According to the technical scheme, the safe protection supporting column comprises protection pieces, a column body, a bottom fixing piece and a supporting column body, the lower portion of the column body is fixedly installed on the ground through the bottom fixing piece, and a vertical cavity is formed in the column body; the supporting column body is inserted in the vertical cavity and is in clearance fit with the vertical cavity, the top end of the supporting body is connected with the bottom of the lifting platform, and several ventholes are formed in the column body and communicated with the cavity; a permanent magnet wrapping an elastic cushion is arranged at the bottom of the supporting body, a buffer spring is arranged on the position, corresponding to the supporting column body, at the bottom of the cavity, and an elastic cushion is arrangedat the top end of the buffer spring; an annular installing groove is formed in the top of the supporting column body, an induction coil is arranged in the annular installing groove, and the output endof the induction coil penetrates through the column body and is connected with an electromagnet; the electromagnet and the protection pieces are fixed to the column body and connected, and the protection pieces are aligned with the ventholes.

Description

technical field [0001] This patent relates to a safety auxiliary equipment for a stage, in particular to a safety protection support column for a lifting platform. Background technique [0002] With the improvement of people's living standards, the demand for spiritual civilization has become more and more vigorous, especially for small stages, miniature stages, and community stages. The introduction of stage machinery is a shortcut to upgrade the current small stage, miniature stage and community stage. The introduction of the stage with mobile modules can greatly enrich the expressive force of the stage, improve the form of stage expression, and create a better stage in a limited space. Stage effects, therefore, it is imperative to develop a stage with mobile modules.

Problems solved by technology

[0003] Chinese Patent Publication No.: CN107905576A, published on April 13, 2018, discloses a scissor-type lifting stage, which relates to the technical field of stage machinery equipment, to solve the problem that the gravity of the lifting stage in the prior art is concentrated on the vertically arranged wires. The lifting stage is not stable and the safety factor is low; it includes the support frame, the base of the fixed support frame and the stage board installed on the upper end of the support frame. There are support screws parallel to the stage board between the support frames. , A scissor-type lifting mechanism is provided between the support screw and the stage board. The scissor-type lifting mechanism includes an upper connecting column and a lower connecting column. There are two lifting plates intersected between the two upper connecting columns and the lower connecting column. The upper end of the lifting plate is hinged to the upper connecting column, the lower ends of the two lifting plates are hinged to the lower connecting column, and the supporting screw is provided with a driving mechanism that drives the lower connecting column to move in the opposite direction

However, there is a problem in this type of technology that the movable stage adopts a lifting platform (frame). In addition to the scissor lift mechanism (ie, scissors) and other power mechanisms, it is necessary to use a power mechanism when the scissors have problems or are passive.
